further OS shrinking achieved: mail, sidebar, hyper-v, onedrive, tabletpc, parental controls, windows store, xbox, office, edge, cortana, cloudexperience, internet explorer, retaildemo, smart card, pointofservice, narrator, search, gpuejectdialog and defender are disabled on debloating the system, but they are not physically removed from the vhd. u can complete this task later. all u need to do is copy your vhd someplace else just in case something goes wrong, have takeownership active and delete all instances of the listed components from ur vhd. each time u delete one u have to get registrar reg manager to delete the corresponding registry entries and then use registry first aid to readjust, readdress and remove the links as it sees fit. it is a tedious task but u perform it only once.

Well, I can confirm all of the above, and with a little more patience, u might as well get rid of other functions u do not use. don't forget to save the latest state between changes, though.

I commented my procedure on: http://reboot.pro/to...e-7#entry215500

It is valid for Wimboot and Compact installs

 

Spoiler

 

Also it is a good practice to remove all garbich with CCleaner and then make a full defragmentation with Defraggler before recapture.

 

As said, a lot of unwanted things can be removed safely from the install.wim since the begining, before the first installation using MSMG Toolkit, there is no need to do it manually after installation and using brute force.

 

Just read carefully and completely the instructions on included README file.

some things, actually the albeit sheer majority of them, cannot be removed in advance, though, at least with my means. so brute force is the only way when this is the case. even the junctioning of things out to a ramdisk is, in a sense, brute force. but, what else can we do? of course, what I have been able to remove your way in advance, I already have. but there still are some things which have not been removed. other things have had their functionality removed, but they are still physically present.

I can confirm that the removal of the list works on other 19042 builds. this time, to make it as close as possible to the end of the install process, I made the deletions right after the completion of driver setup to have everything in order in device manager. it is actually the same as doing it later, but it  works in the end. so let us recap the list:

 

mail, sidebar, hyper-v, onedrive, parental, windowsstore, xbox (no registrar deletion, only files and folders, pls), office, edge, cortana, cloudexperience, internet explorer, internetexplorer, retaildemo, smartcard, smart card, pointofservice, narrator, search, xgpuejectdialog, defender, paint, snipping, update, perceptionsimulation, servicing (leave the trusted installer executable, though), defrag, backup, restore.

 

all these but xbox (see above) need to be erased in the registry thru registrar registry manager, and then its contents need to be deleted from the disk (files, folders and any occurrence). the links should be readjusted by registryfirstaid.

 

the whole process took me about 4 hours. I am sure everything could be eased by a few scripts.

another big space user is the software of a powerful videocard which comes bundled to the drivers. the videocard driver install can be shrunk any further by [Guru3D.com]-NVSlimmer (in my case it is a nvidia card, but I am positive u can find its ati parallel on guru3d.com). better is to install the drivers after the slimming down process.

 

after that, at least as far as nvidia is concerned (I don't know about ati, so dont try if u dont feel like, or do try if u have already backed up ur vhd), u can delete all possible content from \program files\nvidia and \...\nvidia corporation, \program files (x86)\nvidia and \programdata\nvidia and \...\nvidia corporation - dont even try to delete what u have not been able to because it is already open in taskmgr.

 

Still for nvidia cards (again, I dont know about ati), I found nvcleaninstall.exe (I unfortunately do not remember where), which can do the job above by simply enabling u to select what to install (I would choose only the drivers, which include the control panel that u can adjust some features from) + enable or disable some features, all this straight from the exe file from nvidia. I guess this solution is the better one.

here is another one of the branches that want pruning - recovery, so type recovery in swiftsearch and get it outta the disk, then type recovery in registrar registry manager and get it outta the registry.

well, while trying the pruning of another build to see if it works I just came across another bunch of branches to hopefully get rid of - by running bloatbox, I noticed a whole list of "modern" bloating apps to try to delete; well, some it does delete, while others it cannot. among the latter, I found a couple of apps that belong to the list I posted above, which I got rid of in the way described. the rest of them, I will try and see if I can delete the old way. I will tell u the ones I have managed to erase. If u r eager to try urselves, do as I did and start from the first and work ur way down the bloatbox list. see u later.

I have recently found out that the bitlocker stuff can safely be taken out as well.

I have also found out that, by means of process explorer, I can learn what syswow64 dlls a favorite program needs in order to work ok. then, copying them to a safe place before running winreduce and then copying them back later can make that favourite program work even with the reduction (it is technically the same as copying back all files from the syswow64 root, the only difference being the space occupied). the procedure works 7 times out of 10. at the end of the day, i have reached vhd and wim sizes closer to the ones wimb and alacrán have advertised without any "nostalgic suffering". the reduction I am talking about does not concern winsxs (I am still copying manifests back to its original position to make everything work, as before). but if u only have a couple of favorite programs, the syswow64 reduction gain is at least half a gb on the vhd and a bit more on the wim.
